  • Description

This Painted Steel Round Trailer Axle has a carrying capacity of 3500lbs. This is a listing for the Axle beam and spindles. The Hubs are not included. The Spindles are welded into the beam of the Axle as pictured.  These 3500lb Round Steel Trailer Axles are made of round steel tubing that measures 2 3/8 inches in diameter. This 3,500lb Painted Steel Trailer Axle will typically use 3500lb Trailer Hubs with a 5 Lug Pattern.

This 3,500lb Trailer Axle has tapered spindles that use the following bearing sizes and grease seal size:

Inner Bearing 68149 or 1 3/8 inch inner diameter

Outer Bearing- 44649 or 1 1/16 inch inner diameter

Grease Seal- 1.719 inches inner diameter

Each 3500lb Painted Steel Trailer Axle we sell is equipped with the Standard 4 Hole Brake Flange for mounting Trailer Brakes.  The Castle Nut and Spindle Washer are included with the axle. Some of our Painted Steel Trailer Axles come with Pre-Mounted Spring Seats for specific measurements. The Axles listed without pre-mounted spring seats will include the spring seats for you, the customer to weld to your specific measurements.  It is very important that you do not weld your spring seats outside the range listed. Using an axle to long may cause a leverage issue, leading to pre-mature bending or damaging to the ends of the axle. An axle that is to short will cause the tires to rub on the frame of the trailer.  

Check the Hub Face Measurement and overall measurement below, as well as the if the Axle comes with pre-mounted spring seats.

Hub face measures: 88 inches

                -Hub Face measurement refers to the outside face measurement, from one trailer hub across the axle to the outside face of the trailer hub across from it.

Overall length measures: 93 inches

Spring Seat Are Not Welded to the Axle (but are included)

Spring Seats need to be welded on the axle with the centers measuring between 70 inches to 76.5 inches. Using Spring centers outside this range will effect the strength and fit of the axle on your trailer. If you need to find a better fit axle check our other listings or contact us for assistance.
